In long form of periodic table elements are classified into four blocks s, p, d and f based on their electronic configuration. Periodic properties and other physical properties usually show a regular pattern of change within a group or along period with some irregularities.

In which of the following set of elements first element having higher electronegativity than second element on Pauling scale?

Options:

Answer:
A
Solution:

Electronegativity generally decreases down a group. However, Ga (1.81) is more electronegative than Al (1.61) due to poor shielding by d-electrons.

 

The final answer is
